Answer 1

Use array in name attribute that will hold the selected options

<div class="menu">
    @php
        use App\Mailers;
        $mailers = Mailers::all();
    @endphp
    <select multiple name="mailId[]">
        @foreach ($mailers as $mailer)
            <option value="{{ $mailer->id }}">{{ $mailer->fname }}</option> 
        @endforeach
    </select>
</div>

As you are using a form you will get the form values in controller in Request object. So in controller

foreach ($request->mailId as mail_id) {
    //here what you need to do with the ids.
}

It's a bad practice to use php in blade/view. Load variables from your controller instead.
